Based on the search results, "HHB155" does not appear to be an officially and widely published model number for Hansun rock breakers. However, similar models such as RHB155 and HB155G were found, and many suppliers often import and distribute models that may have slight variations in model numbers. Therefore, I will provide information based on these models and assume that HHB155 has equivalent characteristics. 1. Overview: Manufacturer: Hansun (China) or another OEM manufacturer. Model (assumed): HHB155 (based on RHB155 and HB155G). Segment: Large hydraulic breaker, belonging to the heavy-duty rock breaker segment, specialized for large-scale construction and mining projects. Applications: Commonly used in demolition of extremely large and robust structures, industrial-scale quarrying, mineral mining, demolition of extremely large volumes of concrete, road construction, leveling, tunneling, and bridge construction. Suitable Excavators: Suitable for large excavators, equivalent to PC280 – PC360 (28-36 tons). 2. Technical Specifications (based on RHB155 and HB155G): Chisel Diameter: 155 mm (phi 155mm). Breaker Weight: Approximately 2573 kg (HB155G) [3]. Operating Pressure: 160-180 kg/cm² (equivalent to 16-18 MPa or 160-180 bar) (RHB155) [1], 180-200 kg/cm² (HB155G) [3]. Oil Flow: 180-240 liters/minute (RHB155) [1], 200-260 liters/minute (HB155G) [3]. Impact Frequency: 300-450 bpm (RHB155) [1], 250-400 bpm (HB155G) [3]. Excavator Weight (suitable): 28-35 tons (RHB155) [1], 28-36 tons (HB155G) [3]. Chisel Length: Approximately 1500 mm (HB155G) [3]. 3. Advantages of Rock Breakers (in general): High Performance: Models in this segment are designed to have strong impact force and high material breaking efficiency. Durability: Manufacturers often focus on product durability to withstand harsh working conditions. Competitive Pricing: Compared to brands from Korea or Japan, rock breakers from China are often more competitively priced. 4. Common Applications of HHB155 (expected): Demolition of extremely large, robust structures. Industrial-scale quarrying. Mineral mining. Demolition of extremely large volumes of concrete. Road construction, leveling. Tunneling. Bridge construction.
